If you have a squeaky alternator belt, there are a few things you can do to try to fix it. First, check to see if the belt is loose. If it is, tighten it up. If that doesn’t work, you can try spraying some WD-40 on the belt. Let it sit for a few minutes, then wipe it off. If that doesn’t work, you may need to replace the belt.
What Causes Alternator Belt to Squeal?
If your alternator belt is squealing, it could be due to a few different factors. The most common cause is that the belt is simply too loose.
You can easily adjust the belt tension yourself by loosening the alternator adjustment bolt and sliding the alternator to the left or right, depending on which way the belt is too loose. If the squealing persists after you’ve adjusted the belt, it could be an indication that the belt is worn out and needs to be replaced.
Another possible cause of squealing alternator belts is that the pulleys they’re running on are misaligned. This can usually be fixed by loosening the bolts that hold the alternator in place and realigning the pulleys.
If the squealing is still occurring after you’ve done this, it’s possible that one of the pulleys is damaged and needs to be replaced.
If your alternator belt is squealing, don’t ignore it. While it may not seem like a big deal, if left unchecked, it can cause serious damage to your alternator or other engine components. Be sure to check the belt tension and alignment, and if the squealing persists, replace the belt.

If your car’s belt is starting to squeal, you may be wondering if WD40 can help. While WD40 can temporarily quiet a squeaky belt, it’s not a long-term solution. The belt will eventually need to be replaced.
